Abstract: Methods and systems are disclosed for providing location services for user equipment (UE) devices in a radio access network (RAN) such as a Fifth Generation (5G) RAN. Location services may be supported by separate positioning domains that may include a Device to Device domain, a RAN domain and a core network (CN) domain. The RAN domain may include a location server function (LSF) that may support positioning services autonomously within the RAN or in collaboration with a D2D or CN domain. The CN domain may include a location server (LS) that may support control plane and/or user plane location. The RAN domain may enable high volume and low latency location service whereas the CN domain may enable high accuracy service and services for external clients.

Abstract: Techniques to support emergency voice-over-Internet Protocol (VoIP) calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE communicates with a visited network to send a request to establish an emergency VoIP call. The UE interacts with a location server instructed by the visited network to obtain a first position estimate for the UE. The UE performs call setup via the visited network to establish the emergency VoIP call with a PSAP, which may be selected based on the first position estimate. The UE may thereafter perform positioning with the location server to obtain an updated position estimate for the UE, e.g., if requested by the PSAP.

Abstract: Techniques for supporting a control plane solution for location services and positioning are described. In an aspect, an Evolved Serving Mobile Location Center (E-SMLC) may communicate with a Mobility Management Entity (MME) to support location services and positioning for a UE. In one design, the E-SMLC may receive a location request from the MME, perform a positioning procedure with the UE in response to the location request, and send a location response to the MME after completing the positioning procedure. For a UE-assisted or UE-based positioning procedure, the E-SMLC may send a downlink positioning message to the UE via the MME and may receive an uplink positioning message from the UE via the MME. For a network-based positioning procedure, the E-SMLC may send a network positioning request message to an eNB via the MME and may receive a network positioning response message from the eNB via the MME.

Abstract: Techniques for supporting location services for a home Node B (HNB) and its user equipments (UEs) are disclosed. In an aspect, location services may be supported for a UE by having an HNB inter-work between user plane and control plane location solutions. In one design, the HNB receives a request for a location service for the UE and communicates (i) with a location server via the user plane location solution and (ii) with the UE via the control plane location solution to support the location service for the UE. The HNB inter-works between the user plane and control plane location solutions. In another aspect, a location server may be used to support assisted GNSS (A-GNSS) for HNBs and UEs. In one design, an HNB exchanges PCAP messages with the location server via an HNB GW and exchanges RRC messages with a UE to support a location service for the UE.

Abstract: Techniques are disclosed for increasing the reliability of transferring data via in-band signaling in a audio channel of a communication network. Techniques include causing an audio decoding process to modify the decoding of audio signals for the audio channel based on obtaining an indication of in-band signaling. The modified decoding may replace an adaptive de-jitter buffer by a static de-jitter buffer or increase the buffering time of an adaptive de jitter buffer. The decoded audio signals may be provided to an in-band message detector, an audio encoder or an audio playback device based on the indication of in-band signaling. The techniques may be employed by a user equipment, a media gateway control function or a media gateway to improve the reliability of in-band transfer of a minimum set of data (MSD) for a Next Generation eCall.

Abstract: Techniques are presented for receiving, at a discovered secure user platform location (SUPL) server (D-SLP) a request from a device for authorization to access a second D-SLP, where the D-SLP provides location services to a first service area comprising a venue or building. The second D-SLP provides location services to a second service area larger than the first service area authenticating information from a Home SLP (H-SLP) received as part of the request to access the second D-SLP. Techniques involve communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.

Abstract: Disclosed are systems, methods and techniques for determining or inferring a status or fault for a portion or aspect of a global navigation satellite system (GNSS). For example, fault messages may be received from multiple mobile devices where fault messages provide indicators indicative of events or conditions. Fault indicators in received fault messages obtained from messages received from two or more of the mobile devices may be combined to infer a status or fault of at least a portion of a GNSS. Augmentation parameters conveying information related to an inferred fault may be transferred to a mobile device to improve GNSS location of the mobile device.

Abstract: Techniques are discussed for conveying frequency error characteristics for a plurality of cell transceivers from a server to a mobile device to enable the mobile device to determine an optimum or near optimum period of coherent integration of a downlink signal from one or more of the plurality of cell transceivers based on the frequency error characteristics. The coherent integration of the downlink signal may be to support a downlink terrestrial positioning method such as the Observed Time Difference of Arrival (OTDOA) method for Long Term Evolution (LTE) and the downlink signal may be a Positioning Reference Signal (PRS). A mobile device may perform downlink signal integration for longer periods than the optimum period for coherent integration by combining coherent integration results using non-coherent integration. The optimum period may achieve maximum or near maximum signal to noise ratio.
